In an article dated September 22, 2016, it was revealed that a Swedish scientist has become the first known researcher to begin attempts to modify genes in healthy human embryos—a practice which has been, and for many still is, considered “taboo.” Critics are concerned that people will begin to use such technology to create “designer” babies, or that such research could unintentionally create a new genetic disease; however, the scientist involved says he plans to use the embryos for no more than 14 days, in which time he may be able to discover new ways to treat infertility, prevent miscarriages, and use stem cells to treat various diseases.

“Lanner is planning to methodically knock out a series of genes that he has identified through previous work as being crucial to normal embryonic development. He hopes that will help him learn more about what the genes do and which ones cause infertility.”
